如何在android中绘制多个形状，一个接一个类似垂直方向的线条布局

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.RectF;
import android.util.AttributeSet;
import android.view.View;

public class CustomView extends View {
    private Paint paint;
    private int shapeCount = 5; // 绘制的形状数量
    private int shapeSpacing = 20; // 形状之间的间距

    public CustomView(Context context) {
        super(context);
        init();
    }

    public CustomView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public CustomView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        paint = new Paint();
        paint.setColor(Color.BLACK);
        paint.setStyle(Paint.Style.FILL);
        paint.setStrokeWidth(5);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        int width = getWidth();
        int height = getHeight();

        int shapeWidth = width / shapeCount - shapeSpacing; // 每个形状的宽度

        for (int i = 0; i < shapeCount; i++) {
            int left = i * (shapeWidth + shapeSpacing);
            int top = 0;
            int right = left + shapeWidth;
            int bottom = height;

            RectF rectF = new RectF(left, top, right, bottom);
            canvas.drawRect(rectF, paint);
        }
    }
}

<com.example.myapplication.CustomView
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
